Description
Auto Replace
Select a region · mass-break · mass-fill — server-side, so blocks stay gone.
AutoReplace is a lightweight Fabric utility for Minecraft 26.2. Select a box like Litematica and break or fill the entire area in one action. Breaks and fills are executed on the server, so nothing reverts in singleplayer or multiplayer.
📋 Features
- Area selection — right-click two corners (cyan outline, Litematica-style)
- Mass break — break one block inside the selection → matching blocks in the box break server-side
- Mass fill — pick a block from your hand or the world and fill the selection automatically
- Simple Z menu — clean panel with toggles, tooltips, and a fill block preview
- Server authority — no ghost blocks / no "blocks come back" failure
- Paper plugin (optional) — same-network support for Paper/Spigot multiplayer servers
- Safety caps — max 4096 blocks per action, range checks, unbreakable blocks ignored

- Press Z to open the menu
- Enable Selection mode
